Agate and Caledonite Chemical Formula
While comparing Agate and Caledonite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Agate and Caledonite chemical formula.
- Chemical formula of Agate- SiO2
- Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)
Agate and Caledonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Agate and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Agate and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Agate is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
